Solder paste misprint cleaning

1. A method comprising: receiving, by one or more processors, solder paste information, wherein the solder paste information describes a solder paste used in assembly of a printed circuit board, wherein solder paste information includes a density of a metal solder in the solder paste, a density of a flux material in the solder paste, an adhesive force of the flux material; determining, by the one or more processors, a minimum magnetic force required for removing a misprint of the solder paste from the printed circuit board based, at least in part, on the solder paste information; receiving, by the one or more processors, electromagnet information, wherein the electromagnet information describes an electromagnet used in cleaning of the misprint of the solder paste on the printed circuit board; determining, by the one or more processors, an amount of solder paste used in the misprint; determining, by the one or more processors, a component force applied to the misprint of the solder paste based on the amount of solder paste used in the misprint and the solder paste information, wherein the component force comprises at least one or more of the following (i) a gravitational force associated with the metal solder, (ii) a gravitational force associated with the flux material, and (iii) the adhesive force of the flux material; determining, by the one or more processors, a minimum amount of power to provide the electromagnet to induce the minimum magnetic force in the electromagnet, wherein the determination of the amount of power is based, at least in part, on the electromagnet information and the component force applied to the misprint of solder paste; and adjusting, by the one or more processors, an amount of power applied to the electromagnet to at least the determined minimum amount of power to clean the misprint of the solder paste from the printed circuit board.

2. The method of claim 1 , the method further comprising: receiving, by the one or more processors, a misprint location of the misprint of the solder paste on the printed circuit board; moving, by the one or more processors, the electromagnet to the misprint location; and activating, by the one or more processors, the electromagnet upon arrival to the misprint location, wherein the electromagnet removes the solder paste from the misprint location upon activation.

3. The method of claim 1 , the method further comprising: receiving, by the one or more processors, an image of the printed circuit board; comparing, by the one or more processors, the image of the printed circuit board to a second image, wherein the second image depicts a printed circuit board with correctly printed solder paste; and in response to the comparison of the image of the printed circuit board and the second image, determining, by the one or more processors, at least one misprint location of the solder paste on the printed circuit board.

4. The method of claim 1 , wherein the determination of the amount of solder paste used in the misprint is based on an image of the misprint.

5. The method of claim 1 , wherein the determination of the amount of solder paste used in the misprint is based on a pad size associated with a location of the misprint.
